Arguments: plot-widget
Returns the value of the x-axis-2 property of a plot-widget
. The value may be set at creation
time by passing the x-axis-2 initarg to
make-instance when creating a
plot-widget, or any time later by calling (setf x-axis-2).
The x-axis-2 of a plot-widget
is an optional secondary horizontal
axis of the widget, and lies along the top side of the plot. This
axis will be drawn only when one or more of the chart objects are
explicitly associated with this secondary axis in
the chart-objects property.
The value of the x-axis-2
property should be an instance of the
plot-value-axis
class, and
holds properties that determine how the axis is drawn and the range of
values that it displays. The properties are inherited from the
value-axis
and chart-axis
classes.
The value of this property will always be a plot-value-axis
instance. If you do not pass a
plot-value-axis
instance as
the value of the x-axis-2 initarg when creating a
plot-widget
, then a default
instance is created automatically, even though it may never be drawn.
